The Grand Seiko SBGM221 (ref. sbgm221g) is an automatic gmt watch, with a 39.5mm stainless steel case, 13.7mm thick, powered by the 9S66 movement and a 72-hour power reserve. Water resistance is rated to 30m, under a sapphire crystal. Manufacturer MSRP is $5,400.
Grand Seiko SBGM221 is widely praised for its exceptional dial finish, highly polished hands and indices, and elegant design. Owners consistently highlight the stunning craftsmanship, with specific mention of the up to 11 hand-polished facets on its rectangular markers. The reliable 9S66 movement is noted for its 72-hour power reserve and true GMT functionality, tested beyond Chronometer specifications. Some enthusiasts desire a bidirectional 24-hour bezel, which the Grand Seiko SBGM221 lacks, and its 13.7mm thickness and 19mm lug width are noted as potential limitations. On balance, owners rate the Grand Seiko SBGM221 highly for its exquisite finishing and elegant, comfortable design.
